Find out the symptoms that could mean you have a sexually transmitted infection (STI).

Many people with sexually transmitted infections (STIs) don't get symptoms, so it's worth getting tested even if you feel fine. If you think you have an STI, the earlier you're tested, the sooner treatment can be given if it's needed.

An STI can be passed from one person to another through sexual contact, including vaginal, anal and oral sex. You can get or pass on an STI whoever you're having sex with.

These symptoms don't necessarily mean you have an STI, but it's worth seeing a doctor so you can find out what's causing the symptoms and get treatment.

For example, it's possible to get thrush without having sex, but it can cause STI-like symptoms, such as soreness, itching and discharge. Thrush is easily treated – find out more about treatment for thrush.
